Backend Implementation

1. Environment Configuration

# .env
PAYMENTS_AI_API_KEY=sk_sandbox_your_secret_key
PAYMENTS_AI_ORG_ID=org_your_organization_id
PAYMENTS_AI_WEBSITE_ID=web_your_website_id
PAYMENTS_AI_API_URL=https://staging-api.payments.ai
NODE_ENV=development
PORT=3000

2. Configuration

// backend/config/payments-ai.js
require('dotenv').config();

const config = {
  apiKey: process.env.PAYMENTS_AI_API_KEY,
  organizationId: process.env.PAYMENTS_AI_ORG_ID,
  websiteId: process.env.PAYMENTS_AI_WEBSITE_ID,
  apiUrl: process.env.PAYMENTS_AI_API_URL || 'https://api.payments.ai',
};

if (!config.apiKey || !config.organizationId) {
  throw new Error('Missing required Payments AI configuration');
}

module.exports = config;

3. API Client

// backend/lib/payments-ai-client.js
const axios = require('axios');
const config = require('../config/payments-ai');

const paymentsAI = axios.create({
  baseURL: config.apiUrl,
  headers: {
    Authorization: `ApiKey ${config.apiKey}`,
    'Content-Type': 'application/json',
  },
  timeout: 30000,
});

paymentsAI.interceptors.response.use(
  (response) => response,
  (error) => {
    if (error.response) {
      console.error('API Error:', {
        status: error.response.status,
        message: error.response.data,
      });
    }
    return Promise.reject(error);
